Try this....I took my trusty Dremel and cut that little arm off (thanks John!!). be carefull not to cut into the actually butterfly arm because it is brass. Cut it just until you can barely see anysilver where you were cutting, then use a pair of plyers to work it off. Then go get you a 5/32 Nose steering control horn and bolt it on! That way if you swich planes for whatever reason you can adjust it accordingly.
